The objective of this study was to evaluate the resin-ceramic adhesion of a long-carbon-chain silane (LCSI)-containing resin cement.
Polished lithium disilicate ceramic discs were etched with hydrofluoric acid and randomly assigned into four groups; (PSAP), cemented using a silane-free resin cement with no prior priming; (PSAP-S), primed using a silane-containing primer before cementation using a silane-free resin cement; (PSAU), cemented using a LCSI-containing resin cement with no prior priming; (PSAU-S), primed as for the group (PSAP-S) and cemented using a LCSI-containing resin cement. The cemented blocks were sectioned into microbeams. The resin-ceramic microtensile bond strength (μTBS) was measured at 1 week and after thermocycling. The failure modes of the tested microbeams were evaluated.
The μTBS of the LCSI-containing and silane-free resin cements, either with or without a prior priming step, did not significantly differ. The adhesion of the LCSI-containing resin cement to lithium disilicate ceramic, either with or without a prior priming step, did not significantly deteriorate after artificial aging.
The long-carbon-chain silane (LCSI) monomer incorporated in the resin cement eliminated the need for a silane priming step of a hydrofluoric acid-etched lithium disilicate ceramic.
本研究的目的是评估含长碳链硅烷(LCSI)的树脂水门汀与树脂陶瓷的黏附力。
用氢氟酸蚀刻抛光的二硅酸锂陶瓷圆盘,并随机分为四组;(PSAP),使用无硅烷树脂水门汀粘结,不进行预涂底漆;(PSAP-S),在使用无硅烷树脂水门汀粘结前,先用含硅烷的底漆进行预涂;(PSAU),使用含LCSI的树脂水门汀粘结,不进行预涂底漆;(PSAU-S),按照(PSAP-S)组进行预涂,然后使用含LCSI的树脂水门汀粘结。将粘结块切成微梁。在1周和热循环后测量树脂-陶瓷微拉伸粘结强度(μTBS)。评估测试微梁的失效模式。
含LCSI和无硅烷的树脂水门汀,无论有无预涂底漆步骤,其μTBS均无显著差异。含LCSI的树脂水门汀与二硅酸锂陶瓷的粘结力,无论有无预涂底漆步骤,在人工老化后均无显著下降。
树脂水门汀中掺入的长碳链硅烷(LCSI)单体消除了对氢氟酸蚀刻的二硅酸锂陶瓷进行硅烷预涂底漆步骤的需要。
